public class IntImmutableList
extends AbstractIntList
implements IntList, RandomAccess, Cloneable, Serializable

A type-specific array-based immutable list; provides some additional methods that use polymorphism to avoid (un)boxing.

Instances of this class are immutable and (contrarily to mutable array-based list implementations) the backing array is not exposed. Instances can be built using a variety of methods, but note that constructors using an array will not make a defensive copy.

This class implements the bulk method getElements() using high-performance system calls (e.g., System.arraycopy()) instead of expensive loops.
